Oh wait, I lied--I have stolen as an adult. I used to work for this crappy little jewelry store in a mall--they sold cheap jewelry mostly aimed at teenagers. Working for them was a stressful, anxiety inducing nightmare. They employed the biggest drama queens in the manager positions, and people who could not leave their issues at home. I used to babysit one of the manager's little kids without pay (I told her not to worry about it, because she was always in financial trouble...of course, she took advantage of my doing her a favor...), I had to report another manager to the district manager for telling me that she wouldn't employ black people at the store, the district manager was a raving bitch, and I was often left to work by myself, without break, for 10-12 hour shifts. I eventually put in my two week notice after putting up with it for a year, and was so pissed off with the company, that I took home jewelry with me after I closed the store. Leave me alone in there for 12 hours, having to cater to the customers, skip my lunch, and make a mad dash to the bathroom if I have to pee? Well, fuck you! I'm taking this choker!
It doesn't really excuse the stealing, and now that I'm older and wiser, I probably wouldn't do it again--and I wouldn't stay at such a miserable job for so long, either. I was just another disgruntled employee.
